Hi
As far as I can see then I currently having WU (they refere to slots?)
WU01 is the cpu and withing /var/lib/fahclient/work/01 find a log file called logfile_01.txt:
Code: Select all

Folding@Home Gromacs GB Core
Version 2.27 (Dec. 15, 2010)

Preparing to commence simulation
- Ensuring status. Please wait.
- Looking at optimizations...
- Working with standard loops on this execution.
Examination of work files indicates 8 consecutive improper terminations of core.
- Expanded 825690 -> 1402156 (decompressed 169.8 percent)
Called DecompressByteArray: compressed_data_size=825690 data_size=1402156, decompressed_data_size=1402156 diff=0
- Digital signature verified

Project: 9035 (Run 154, Clone 0, Gen 1055)

Entering M.D.


The cpu/WU01 does not contain any subfolders

However the others does (/var/lib/fahclient/work/00/01) and in here I found a log that looks like this

with a bit of luck then I got an A7 core and this folder /var/lib/fahclient/work/01/01 was created with a log called md.log:

I'm asking you for the md.log associated with the A4 problem you reported originally. You found a log from Core_21 and Core_a7. You need to capture the log when an A4 WU has been downloaded AND just after the error occurs. That log may say
WU00:FS00:0xa4 or
WU01:FS00:0xa4 or
WU02:FS00:0xa4 or even
WU03:FS00:0xa4

It will be in /var/lib/fahclient/work/??/01 where the ?? will be the number of the WU, not necessarily the number of the slot.

If you no longer have a problem, fine. If it breaks again, please follow my instructions.

Re: Cannot fold A4 cpu but can fold A7

Postby beer » Thu Feb 22, 2018 4:13 am

Sorry for not being clear before. The folder /var/lib/fahclient/work/??/01 where ?? match the WU where I have the problem with the A4 core is never created. I can find the the /var/lib/fahclient/work/??/ folder but there is no sub folders in it and it is no subfolder being creating before the problem arrives or after the problem happens. So I am unable to to capture that file since it never is created or existed in the first place.
The only log I can find in that folder looks looks like:

And everytime it fails to start then another log is created jist with a time stamp in the name.

The only workaround is still to to drop all the a4 cores I resive unto I got an A7. I have been looking around in the userinterface but I cannot find any place that do say I will like to fold A7 cores

Re: Cannot fold A4 cpu but can fold A7

Postby bruce » Thu Feb 22, 2018 5:20 pm

That sounds like a permissions problem.

FAHClient normally runs as a service within a special user name created at install time. All subdirectories of /var/lib/fahclient should be owned by that user, not by your user name or by root. (The username is "fahclient" or something like that.) If that user cannot create new files whenever and wherever it wants inside of /var/lib/fahclient and later remove them, it will probably fail in the way you've described.

I'm assuming the client is always started using "sudo /etc/init.d/FAHClient start," whether it's started automatically at boot time or you manually invoke that script.

You are talking about this line that I found in the log?
20:03:10:WU01:FS00:Running FahCore: /usr/bin/FAHCoreWrapper /var/lib/fahclient/cores/fahwebx.stanford.edu/cores/Linux/AMD64/Core_a4.fah/FahCore_a4 -dir 01 -suffix 01 -version 704 -lifeline 659 -checkpoint 30 -np 6

I am not the expert in sudo but last time I looked into then the user was either and preveliges was in # User privilege specification and # Allow members of group sudo to execute any command. I cannot see any trace of FAH in my /etc/sudoers-file:
Code: Select all
#
# This file MUST be edited with the 'visudo' command as root.
#

# See sudoers(5) for more information on "#include" directives:

I am not an expert in permission but the below lines means that everyone has acces to everything in those folder?
Code: Select all

beer@debian:/var/lib/fahclient/work$   


And there is something that I dont undertand (I presume you are right). When FAH creates this folder /var/lib/fahclient/work/01 then fah would also have permission to create subfolders so how can it be a permission problem?

Re: Cannot fold A4 cpu but can fold A7

The script "/etc/init.d/FAHClient" that I mentioned above will start the FAHClient service provided it is started with root privileges and the files will, in fact, then belong to that special user I mentioned. On the other hand, if you start FAHClient manually, the files created will belong to you. If a mixture of file ownerships has been created, it needs to be resolved.

Is it possible that FAHClient has been started by two different methods?

Re: Cannot fold A4 cpu but can fold A7

Postby beer » Fri Feb 23, 2018 6:20 am

I dont recollect that I have setup anything speciel thus time from my own user (but my memory could be wrong. So lets assume it is). Do you know how I can check what privileged that is running with?

Another thing that puzzles me is that both A7 and A4 is managed by the same slot. The A7 runs perfectly find and only A4 cores fails. So we are hunting down the user that starts FAHClient. And that user have writing privileged if it runs A7 but do not have all the privilege with running A4.
ANd that user can write /var/lib/fahclient/work/00/ but not into /var/lib/fahclient/work/00/01/?

I am a bit if noob into this. How do I check the stuff needed so we can progress on the problem?

Check the ownership of
/var/lib/fahclient/work/* and any subdirectories of each file you find. (You can ignore anything that's missing.)

Re: Cannot fold A4 cpu but can fold A7

Postby bruce » Sat Feb 24, 2018 6:09 pm

What WU is shown in /var/lib/fahclient/work/02/logfile_01.txt? (I suspect that all of the other 577 byte files contain the same information.)

That WU is clearly having difficulties though I'm not sure what the problem is.

I suspect the problem will be cured if you run ./fahclient.exe --dump 02 but I'd like to know more about what's currently happening there.
You'll probably need to pause all WUs before doing that.

(From the information I see here, we don't know which slot is currently processing that WU.)

Also, there's a chance that this report may help. Subject: Core a4 WUs segfaulting on kernel 4.15
Apparently the fix found there also applies as far up as kernel 4.8 so it's worth a try.

Core a4 WUs segfaulting on kernel 4.15

Postby butc8 » Sat Feb 24, 2018 6:47 pm

Ever since upgrading the kernel to 4.15 core a4 WUs have stopped working (core a7 still work). The WU doesn't error out but is interrupted and restart, hence making no progress. Log attached.

Having a look a the output of dmesg, it seems as if there is a segfault.

Code: Select all
[ 7290.795572] FahCore_a4[5393]: segfault at ffffffffff600400 ip ffffffffff600400 sp 00007f316fa83d88 error 15
[ 7350.913653] FahCore_a4[5626] vsyscall attempted with vsyscall=none ip:ffffffffff600400 cs:33 sp:7f395887bd88 ax:ffffffffff600400 si:7f395887bc2a di:7f395887bdc8


This message shows up everytime the core is restarted.

My specs are

Dell Inspiron 7559
Core i5-6300HQ
Arch Linux
Linux kernel 4.15.5-1

Thank you :)

I think that I read somewhere that this kernel was full of bugs and should be avoided (and not specifically for FAH) ... I don't remember to what exact version it was applying, but you might be facing one of those bugs ...

I have discovered a workaround, adding the kernel parameter "vsyscall=emulate" seems to fix the problem.

Hi
I think I have the same situration:
viewtopic.php?f=72&t=30654&start=15

I am a bit of a linux newbie. I have tried to google how/where to enter "vsyscall=emulate" on a debian system. But without no good results. Can you point me in the right directions (I am running Debian testing)

No problems here with 4.15.4 and 4.15.7 whatsoever...Ubuntu 17.10 x64

Edit:

Because the Ubuntu kernel seems to have this option set at compile time

Code: Select all
/boot$ cat config-4.15.4-041504-generic | grep -i emulate
CONFIG_LEGACY_VSYSCALL_EMULATE=y
